Maybe their diet would shift but a lot of animals eat ticks. Frogs and toads, many smaller birds like warblers and probably house sparrows and robins, chickens love them, and of course opposums and mice.

Similar for mosquitos. I see the house sparrows around here catching mosquitos all the time. I'm pretty sure dragon flies feed heavily on them too.

Wow I haven't read a good chunk of this list, and I thought I was a sci-fi book afficionado. Thanks for adding to my summer reading list! Might start with either Parable of the Sower or Never Let Me Go.

I did my first track workout on Thursday. Felt good so went for a run yesterday. Took some wrong turns (live in a new city) and ended up doing 15 miles. Today is supposed to be my long run but I might just do a recovery run because I'm so tired!

I tried that out and posted the picture in another comment in this thread (https://lemmy.world/comment/10346090). I think it's better but I have some more to learn. Your photo is brilliant!

Thanks, that's exactly how I took the photo. It was approaching sunset so I think the colors are a little yellow because of that and just how brown the river is. I adjusted the colors like the other comment suggested and I think it looks better:

Thanks, I've been practicing getting the focus sharp. It's a tough battle between my phone's autofocus vs manual bino adjustments and keeping the phone+bino stable. I still feel I have more work to do on that too.

I see cormorants all the time here too, I just loved how this one was screaming at something. On this walk, I saw only one cormorant but 60ish Canada geese (with a ton of goslings!), so the cormorant felt rare today. I also saw a blue heron but he flew too far away for me to get a good picture.

I would also recommend checking out salome. It has a parametric CAD module like you would be used to in SolidWorks. It felt a little less finicky to me than freecad , and I also think it has more controllable STL generation compared to freecad.

I think sometime went wrong with your KDE frameworks description. Looks like the some python notes got in there instead.

Love seeing all the updates! OpenSUSE has been working great for me.

One more thing. Running hydrogen, even in blends of 30% hydrogen/70% natural gas, creates a large amount of extra NOx production. NOx, of course, is a pretty nasty pollutant. We need to redesign our current natural gas burners to help control NOx at high hydrogen blends.

Also, I think we need to be moving towards 100% hydrogen if we want to use combustion as a green replacement for natural gas. However, I don't think many of the appliances that currently use natural gas could safely use 100% hydrogen because of the properties of hydrogen gas. Primarily, I think the flame speed of hydrogen would require us to redesign the various combustors that use natural gas currently so that we don't have flashbacks. Additionally, the hotter burning of hydrogen might cause material failure issues in our current natural gas burners. The research I've done is shown that we could probably get away with 30 to 40% hydrogen, maybe dependent on the exact burner. I don't think moving to 100% hydrogen is feasible without a massive replacement of all of our gas burning appliances.

Oh neat, I actually know a lot about hydrogen-natural gas blends!

I read the report because of this claim:

And now, a team of British researchers has found adding hydrogen to natural gas actually increases how much natural gas leaks from stove burners and boilers because the smaller hydrogen molecules help the larger methane ones escape.

I've never heard of small hydrogen molecules helping larger molecules leak. I was curious what the mechanism for this was. It turns out the report does not make that claim at all. In fact, the report claims the additional leakage from hydrogen blends is most likely just the hydrogen leaking. I didn't run the numbers myself but the data presented seems approximately aligned with that. Hydrogen leaking through fittings is already a well-known and established challenge of blending hydrogen with natural gas. So the central thesis of this news article is completely fabricated.

I am a little surprised the utility companies are going to soon be mixing in hydrogen. I didn't think we we're quite ready to blend in hydrogen into natural gas for the leakage reason, and also because of production scaling issues that we haven't resolved yet. These challenges are likely within reach soon. For example, the United States department of energy has a large research initiative right now to help lower the cost of hydrogen production to be more competitive with natural gas. We also need to make sure that hydrogen is produced in a carbon-free or carbon neutral way, which is probably going to be dependent upon our electrical grid becoming carbon free.

 

I've been passing by this house once every few weeks on a walk, but the chickens have always been near their coop in the back. One of them finally came up to say hello!

 

I was a little surprised by the beauty in Shawnee National Forest. Lots of rock outcroppings and long trails to be found. At least, compared to the rest of Illinois!

 

Hello, I have some fret buzz on my first and second frets of my E and A strings. I am trying to fix this myself because I want to learn. I think this means I need to adjust the truss rod, right?

However, the bolt thing to my truss rod looks completely stripped:

I can't really turn it.

Does that mean I need to make a new nut now if I want to get rid of this buzz?

 

This is one of my old neighbor's chickens. She is probably one of the prettiest I have ever seen. I forgot her breed, anyone know?
